The ignition starter switch is the electrical side of the ignition. As the key moves through its positions, the switch opens and closes the circuits that feed the ignition system, the accessories and the starter. A worn original switch can cause a no-crank condition, stalling, or accessories that cut out. If yours is the cause, this switch replaces it.
